The powerful GSD 22 digital sounder adds detailed sonar data to your compatible Garmin chartplotter over the Garmin Marine Network.
Connect to the on the map page. You also can use Garmin Marine Network
This black-box sounder connects to your chartplotter over the Garmin Marine network to provide high-speed data returns and super-crisp detail. Once connected, any plotter on the network can view the 22's detailed sonar data and overlay it the GSD 22 with Garmin's CANet® to connect to non-network chartplotters.

The gWind transducer features twin-fin technology with 3-bladed propeller for more accurate TWS in lighter air while the twin-fin design gives a more stable TWA. The 3-bladed propeller, unlike a cups design, is always efficient. Combined with optic reading this transducer provides superior accuracy at low wind speeds and also provides for excellent linearity.

The GSD 24 features a vastly improved digital sonar design for superior target definition and deep-water performance.
Get the Whole Picture
With up to 2,000 Watts of transmit power and a high-dynamic range receiver, the GSD 24 brings high-definition imaging to your compatible Garmin chartplotter. The system is dual frequency (50/200 kHz) capable and offers selectable transmit power (600 W, 1 kW and 2 kW, depending on transducer) for pin-point accuracy at depths of up to 5,000 ft (1,500 m). So whether you’re out sportfishing or just keeping an eye on hazardous terrain and reef structures beneath your boat, you’ll see a clearer picture with enhanced separation of images and deeper bottom detection.

The GSD 26 digital sonar ushers in the next evolution of sportfishing technology, providing unrivaled target separation at far greater depths than traditional sonar.
Discover Spread Spectrum Clarity
For serious deep-sea sportfishing, the GSD 26 takes high-definition targeting to a whole new level. With a compatible transducer, the GSD 26’s Spread Spectrum technology scans on multiple frequencies at one time, returning vast amounts of data to the receiver. As a result, you can expect precise, shallow-water-like target separation at much greater depths – up to 10,000 ft (3,000 m).
